The U-200 Harbinger is a heavier-hitting take on the U-100 Lastly. Whereas the Lastly features a more balanced profile, the Harbinger more harshly punishes inaccuracy with its lower rate-of-fire and smaller magazine, in exchange gaining faster muzzle velocity, more favorable aimed characteristics, and a far higher caliber, allowing it to kill standard infantry in just 2 headshots at closer ranges, while maintaining lethality in mid-range encounters.
The weapon's muzzle flash and noise generation is reduced, and the player no longer appears on the minimap when firing. In exchange, the weapon's damage falls off 20 meters sooner and bullet velocity is reduced by 15%.
The rail mounted Darklight Flashlight can illuminate hostile cloaked infiltrators and dark areas but the light can give away your position. The light can be turned on and off with Toggle Attachment hotkey.
It is possible to earn both Ribbons and Medals while using the U-200 Harbinger. Each ribbon is a standard reward for achieving a set amount of kills with the sidearm. Medals are awarded upon reaching kill milestones with the weapon.
